반응 단계
Cyanoacetyldimethylurea is prepared in analogy to Example 1. Instead of dibenzylurea, dimethylurea is employed. The product is worked up by stripping off the acetic anhydride/acetic acid mixture on a rotary evaporator under reduced pressure. The residue obtained in this way is recrystallized from water.
